Uwe Hermann <uwe@hermann-uwe.de> eal _CPUTAPID entry for the LPC2148. I don't know 

if they're the same for all LPC214x, this number is from an Olimex
LPC-H2148. The chip on that board is LPC2148FBD64.

Also fix a few cosmetic issues and comments in the file and add
more docs and pointers to the datasheet.
